There are similarities, of course, as you could expect from any modern language (i.e. created in the 21st century) but if there is something noteworthy about all the recent languages that came out these past years (Kotlin, Ceylon, Swift, Fantom, Gosu), it's not how much they look like Scala but all the features from Scala that they left out.

The Scala experiment produced a lot of interesting results and added a lot of clarity about what features are interesting in a modern language (property, lambda, extension methods, sum/union types, and a few others) but the complexity of Scala's type system and the uncertain shape of its code base (see Paul Phillips' talks) is demonstrating that it's often wise to support fewer features rather than be a kitchen-and-sink language.

I am very excited by this trend of minimalism in languages and the willingness from language designers to say "Interesting feature but it will add too much complexity, so I'm not adding it".

Best of luck to Swift, and I can't wait to see if a language will finally emerge on the JVM to supplant Java (even though this might take a solid decade).
